What looks like a teleporter from science fiction being draped over NASA's James Webb Space Telescope, is actually a "clean tent." The clean tent protects Webb from dust and dirt when engineers at NASA's Goddard Space Flight Center transport the telescope out of the relatively dust-free cleanroom and into the vibration and acoustics testing areas. via NASA http://ift.tt/2gxOxoO
